Inliners International Forums General Discussion Hi Performance Cross Flow Head 250 292

That is very interesting. My first impressions:

I like the shape of the combustion chambers - it reflects current thinking and should burn fast and not need a (large) piston dome.

I like the placement of the exhaust runners but don't think round is necessarily the best shape.

I wonder why the intake port opening is so low on the casting. It looks like there is real estate to move it upward and minimize the effects of a tight short side floor radius. (see my photo above)

It also looks like you have the option to make the valve train either stud-mount rockers or shaft-mount rockers. I like that insofar as I have become a convert to the benefits of shaft-mount.

Symmetrically opposite paired cylinders can be problematic.

I realize you are quite far along in the casting process. I'm just brainstorming some thoughts which no doubt you have addressed. Good luck with this project.
